    The vertical distance between the actual value of y and the estimated value of y. In other words, it measures the vertical distance between the actual data point and the predicted point on the line
    If the observed data point lies above the line, the residual is positive, and the line underestimates the actual data value for y. If the observed data point lies below the line, the residual is negative, and the line overestimates the actual data value for y.

    This study introduces an adaptive method to determine optimal norms for image restoration and super-resolution (SR) models. The approach robustly handles various noise types and adapts regularization based on local image activity.

    Area of Science:

    • Image processing
    • Computer vision
    • Signal processing

    Background:

    • Regularization models are crucial for image restoration and super-resolution (SR).
    • Determining appropriate norm parameters in these models is a significant challenge.
    • Existing methods often struggle with diverse noise types and lack spatial adaptivity.

    Purpose of the Study:

    • To propose a novel method for adaptively determining optimal fidelity and regularization norms in SR restoration models.
    • To enhance the robustness and performance of image restoration techniques across various noise conditions.
    • To introduce a locally adaptive regularization strategy for improved detail preservation.

    Main Methods:

    • A piecewise function inspired by generalized likelihood ratio test for adaptive fidelity norm determination.
